Every marketplace publishes its own photo rules, and no two agree. One wants a 1:1 square, the next wants a 3:4 portrait, and a third caps files at 2 MB while its neighbour allows 10 MB. If you sell on more than one platform, you end up opening a dozen help pages just to resize one product shot.

This cheat sheet puts the headline numbers for 35+ platforms in one place: pixel minimums, ratios, file caps, and photo counts. Use it as a fast first check, then confirm the numbers in your own seller account before a large upload — specs change, and many seller portals sit behind a login.

The tightest limits to design around

Four patterns cause most rejected uploads, and they are worth designing around before you shoot anything.

Two pages from the same platform disagree. Airbnb gives 1,024 x 683 px on one page and 1,200 x 800 px on another. Poshmark gives a 3:4 cover on one page and square on another. Noon's two pages differ on ratio. When a platform contradicts itself, upload the larger size and check your own listing page.

Official page versus partner guide. Agoda's 4 MB and 10 MB, Takealot's 10 MB and 2 MB, and Target Plus's 1,000 and 1,200 px all trace back to this gap. Trust the platform's own page first, and test one listing before a full catalogue upload.

Square versus portrait. Walmart, Lazada, and the Meta catalog want 1:1. Zalando wants 1:1.44. Poshmark wants 3:4, and Depop and Vinted guides lean toward 4:5. A square cannot become a portrait without adding empty canvas, so portrait platforms need their own export.

Ceilings, not just floors. Jumia stops at 2,000 px and Lazada's guides cap at 2,000 x 2,000 px, so a 4,000 px camera original is too large and has to be scaled down. And file caps are the quietest killer: Jumia states 2 MB, Temu and Shein use 3 MB, Walmart and AliExpress use 5 MB. A photo that passes one platform's cap gets rejected by another for being several times too large — and the rejection message usually does not say which limit it hit.

A master file that clears most of the sheet

No single size fits every platform, but one master file comes close: shoot or edit one 2,000 x 2,000 px square JPEG in sRGB on pure white, compressed under 2 MB. That sits inside Jumia's 2,000 px ceiling, meets the pixel minimum on the product-photo rows in the tables above, and fits under the tightest file caps. Walmart's recommended 2,200 px and Etsy's 2,000 px shortest side are recommendations, not hard floors, so a 2,000 px master still passes their minimums. If a platform lists a recommended size above your master, upload the larger original there instead of upscaling.

Two groups need their own export. Portrait platforms need a 3:4 version — for example 1,500 x 2,000 px — for Poshmark, Meesho's portrait option, and apparel on Temu and Shein, plus a 1:1.44 version for Zalando. Re-frame these in portrait, because a square cannot become a portrait without adding empty canvas. Property and travel platforms need a landscape export at 2,048 x 1,080 px or larger for Booking.com, and 1,200 x 800 px or larger for Airbnb and Vrbo.

How to work with one set of images

Once the master is locked, the work is exports, not retouching. Shoot and make every image at 2,000 to 2,500 pixels square. Keep a word-free version of every image that carries words, for eBay, Target Plus, and Google. Export a copy per marketplace: smaller files for Etsy, Shein's sizes for Shein, portrait for Poshmark and Zalando. Name files by product, image, and marketplace, so the right set goes to the right place. And check the marketplace's upload screen when you start on a new one, and once a year after that — marketplaces revise their image specs, and this table is dated October 2026.

The part sellers underestimate is the background. Sixteen of the platforms in the wider data require white, and the strictest — Amazon and Walmart — want pure white at exactly RGB 255, 255, 255. A product photographed on a light-grey sweep lands around 246–252 and fails review with no explanation. That is why the master file above is on pure white, and why the cutout behind it has to be genuinely clean, not approximately white. AiLogoFix's background removal service puts product photos on a true pure-white background by hand, so the same master file passes Amazon, Walmart, and every other white-background platform. If the listing also needs a clean logo for packaging or inserts, the raster to vector service turns it into a scalable vector.

Pre-upload checklist

FAQ

What is the best all-purpose marketplace image size?

No single size fits every platform, but a 2,000 x 2,000 px square JPEG in sRGB, under 2 MB and on pure white, clears most of the general marketplaces in this sheet. Fashion and resale platforms with portrait ratios, and property platforms that want landscape, need their own exports.

Which marketplaces want portrait images instead of square?

Zalando asks for 1:1.44 portrait. Poshmark moved its cover photo to 3:4. Temu and Shein list 3:4 for apparel, Meesho allows 3:4, and Depop and Vinted guides lean toward 4:5. Walmart, Lazada, the Meta catalog, and Target Plus stay at 1:1.

Which marketplace has the smallest file size cap?

Jumia states 2 MB across its image pages. Amazon's seller blog also gives 2 MB for A+ Content images, and some Meesho guides quote about 2 MB. Temu, Shein, and one Lazada guide use 3 MB. Because the caps differ so much, export to the smallest file weight first.

Do I need a separate set of photos for each marketplace?

Almost, but not quite. One master file at 2,000 x 2,000 px on pure white, plus a portrait export and a landscape export, covers the overwhelming majority of platforms. The per-marketplace work is resizing, cropping, and compressing — not re-shooting.

Why was my image rejected when it looked fine to me?

The most common silent reasons are a background that is not exactly RGB 255, 255, 255, a file over the platform's cap, text or a watermark on a main image, or a size below the zoom threshold. Check the row for your platform above, and check the file's actual properties — not how it looks on your screen.

Conclusion

Marketplace image rules disagree on almost everything: the size, the shape, the background, how many photos a listing can have. The way through is not to memorise forty sets of numbers, but to build one master file — 2,000 x 2,000 px, square, pure white, under 2 MB — and export from it, with a portrait version for fashion platforms and a landscape version for property platforms. Keep the background truly white, keep text off the main image, and test one listing before you upload a catalogue.

Selling on several marketplaces?

AiLogoFix's specialist team puts your product photos on a true pure-white background by hand, checks every edge, and delivers listing-ready images sized for Amazon, Etsy, eBay, Walmart, and Shopify — so one set of photos passes everywhere, first time.
